To all whom it may concern:

Be it known that I, EMANUEL J. PERRY, citizen of the United States ofAmerica, residing at New Bedford, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements inWashing-Machines, of which the following is a specification.

The invention relates to improvements in washing machines;

It is an object of the invention to provide a washing machine having awashing cylinder therein, which may be swung from the casing to permit adischarge of clothes therefrom that have undergone a washing treatment.

The invention more particularly aims to provide a washing machine with amovable clothes containing cylinder, which may be shifted from themachine by power means to expeditiously permit the clothes to beremoved.

From a more specific aspect, the invention comprehends a power washingmachine, wherein the washing cylinder is connected with swinging armsattached to the casing, which arms are shifted by power cylinders tolift the cylinder bodily from the casing upon the completion of awashing action to allow the clothes to rapidly drop from the cylinder,thereby saving the excessive time generally heretofore employed inremoving clothes from the older types of washing machine.

In the accompanying drawings I have disclosed the preferred embodimentof the invention, but this disclosure is made for the purpose ofillustration only, and the construction and arrangement of the parts aresubject to many changes without departing from the invention.

In the drawings Figure 1 represents an end elevation of one end of thewashing machine; and,

Fig. 2 an end view of the machine, with the clothes cylinder in anextended position.

Referring now more particularly to the drawings, wherein like referencecharacters indicate corresponding parts, the numeral 1 designates thecasing of a washing machine,

which may be of any preferred or conven-' tional structure, the samebeing shown as being supported upon the legs 2. The casing of thewashing machine is provided with a movable segment section 3, hinged tothe main portion of the casing by the hinge 5, said segment carrying apart of the bearing 6, .for a purpose which will hereinafter appear.

Mounted within the washing machine is the washing cylinder 7 Thiscylinder may be of the usual open work construction, or any otherdesirable form, being supported upon a shaft 8 carrying a gear wheel 9that meshes with a gear 10 driven by a pulley 11 carried by a suitableshaft, and operated from any source of power. The cylinder normally ismaintained within the washing machlne, as disclosed in Fig. 1 of thedrawlngs, at which time the segment section 3 is closed, and the shaft 8is resting upon the bearings l2,it being understood that steam. or wateris introduced to the casing 1, and the cylinder revolved for cleansing asupply of clothes placed therein through the movable door 13. Thisconstruction is all common 1n the various washing machines now in use.

Considerable time is generally lost in removing a supply of clothes froma cylinder after a washing action, it having been the practice to rotatethe washing cylinders to a point where the door could be opened, and tothen open a door in the casing and remove by hand the supply of washedclothes. This has required much time and labor. and it has beenappreciated by those skilled in the art that a simple and eflicientmechanism for controlling the washing cylinders whereby 'a supply ofclothes could be expeditiously removed and anew supply placed therein,would be a marked advance in the art.

The present invention, therefore, aims toprovide a mechanism for rapidlyshifting the cylinder from the casing so as to enable clothes to beremoved therefrom. To this end I employ a pair of swinging arms 14, onebeing disposed at each end of the casing, which arms are mounted upon ashaft 16 connected with the casing at one end, and at their oppositeends pivotally engage the cylinder shaft 8. Connected with these arms ata point near the shaft 8, are the piston rods 17 carried by pistons 18movable in the fluid pressure cylinders 19, which are pivoted at a point20, and receive a source of fluid supply through the pipe 21. This fluidsupply maybe water, steam or any equivalent energy, and is introduced tothe cylinders 19 for the purpose of reciprocating the pistons therein.While I have disclosed a cylinder as positioned at each side of themachine, it may be understood that a single cylinder maybe employed, orother power devices may be usedfor moving the arms 14, in a manner whichwill be now described.

When a fluid pressure is introduced to the cylinders 19, the pistons arecaused to reciprocate and swing the. arms 14 upwardly to the positiondisclosed in Fig. 2. To open the segmental section 3 of the casing .1',when the cylinder is to be moved from the casing, link arms 22 areemployed, said arms being pivoted tothe arms 14 at one end, and at theiropposite ends being pivoted to brackets 24 connected with the segmentalsection 3. It will therefore be apparent that when the arms 14 areraised through the agency of the fluid pistons, and their cylinders, thesegment 3 will be swung on its pivot '5 and the entire shaft 8 carryingJits washing cylinder and operating gear 9 odily lifted from the casing1, to the position shown in Fig. 2. The cylinder is maintained in thisposition until the clothes have been removed from the opening therein,controlled by the door 13, whereupon a new supplyof clothes may beintroduced to the cylinder, and by exhausting the fluid pressure in thepower cylinders 19, the washmg cylinder 7 will be again lowered to theposition shown in Fig. 1, the segmental section 3 of t e casing 1 beingclosed so that the section6 of the bearing carried thereby will engagethe shaft 8.

It has been found preferable to provide a means for lockingthe cylinder7 with respect to the arms 14 so-as to prevent a relative movement ofthe cylinder when a supply of clothes has been washed, and it is desiredto shift the washing cylinder from the casing. To this end, I provide alatch 25, whichis mounted upon one of the arms 14, and is formedwithseparated engaging sections, adapted to be drawn toward each other upona manipulation of the handle 26 for the purpose of locking the gear 9carried by the shaft 8 to one arm 14. This lever 26 is actuated when theclothes in the cylinder have been washed, and the gear is locked whenthe cylinder is in such a position that the openlng controlled by thedoor 13 will be in the position shown in Fig. 2 when the entire cylinderis shifted from. the casing. In other words, the cylinder is preferablylocked when the same is to be shifted from the casing so as to be in aposition to most favorably discharge the cleansed clothes. While alocking means is preferable, it is not entirely essential,.and the samemay be dispensed with, should this be desirable; It will likewise be a.parent that any other type of locking mec anism may be employedsuitable for accomplishing the desired purpose.

tion of the bearing for the shaft 8, it is .otally mounted upon pins 28.

preferable that a means be employed for locking this movable section tothecasing 1 when the same is in operation. I have therefore shownswinging latches 27, one at each side of the movable section 3, and piv-When the machine is to be operated, the latches are swung over pins 29carried by the body 1,

and serve to rigidly hold the section 3 in a closed position and againstaccidental displacement due to the rotation of the shaft 8. Obviously,other fastening devices may be used, and I have merely shown the presenttype of fastener as a convenient means of retaining the section in alowered position.

Having thus described the invention, the

operation may\be briefly stated as follows:

Assuming that a supply of clothes has been introduced to the cylinder 7,and the movable section 3 lowered to the position shown in Fig. 1, thepulley 10 is then'operated by a belt or any other source of power,rotating the gear 9, which correspondingly rotates the cylinder 7 withinthe casing. Water or steam is present therein, and the rotation of thiscylinder for a sufficient,period serves to cleanse the clothes containedtherein. After the clothes have been washed the latches 27 are swung tothe position shown in Fig. 2, and the lever 2.6 shifted'to lock thecylinder 7 against movementrelative to the arms 14. Fluid pressure isthen applied to the power cylinders 19 through the feed pipes 31,serving to raise the pistons therein, which pistons, through the pistonrods 17, raise the arms 14, which arms lift the shaft 8, and itscylinder 7 from the casing to the position shown in Fig. 2. It will beunderstoodthat as this cylinder is being moved from the casing, thelink-arms 22 also move the segment 3 on its pivot 5 so as to provide aspace for the passage ofthe shaft 8. The door 13 is opened when thecylinder is in the position shown in Fig. 2, and the cleansed clothesremoved. A new supply of clothes is then introduced to the cylinder andthe fluid pressure in the power cylinders 19 exhausted, which causes thewashing cylinder to again move into the casing 1', as shown in Fig. 1.The arm 26 is then actuated to release the gear 9, and the swinginglatches 27 are shifted so as to engage the pins-29 and lock the'segment3 in position. After the clothes are washed, the operation hereindescribed is repeated, as will be clearlyunderstood.

Having thus described the invention, what I claim; is: a
